TRAXXAS TRX4 Scale Steering Upgrade Aluminium Servo Horn and Link - TRX416025 by GPM  [TRX416025]

Aluminium servo horn and steering link for TRX4

This aftermarket aluminium servo horn and steering link kit is for TRAXXAS TRX4 Trail Crawler setups and is listed as model TRX416025. The 8 piece kit replaces the weaker plastic horn and linkage to reduce flex and improve steering precision on straight steering arm layouts.

The steering link features a counter-clockwise threaded tie rod so length changes do not disturb ball end seating, helping you fine tune toe and steering bias. The midpoint measurement between the ball ends is 77.5mm, a useful datum when checking geometry or swapping links.

Kit contents and notes: supplied with stainless steel mounting screws and a lock nut, the main components are aluminium which cuts wear compared with the stock plastic units. The set suits scale trail crawling builds on the TRX4 chassis where a firmer steering feel is preferred.

Fitting and setup guidance: replace the plastic horn with the aluminium unit using the supplied screws, ensure servo spline alignment before torquing, and use the CCW tie rod for small length adjustments while validating steering centring and travel. This upgrade directly addresses plastic arm weakness and delivers a more consistent steering response at low speeds.
